ATEX-compliant rotary encoders

Absolute rotary encoders for explosive atmospheres

A special challenge for rotary encoders is presented by potentially explosive atmospheres, for example in transfer systems in painting lines, filling/bagging plants, in flour mills, at fuel pumps in filling stations or in geothermal energy.

As an accredited manufacturer of explosion-proof housings we offer ATEX-compliant absolute rotary encoders with housings made of aluminium or stainless steel for hygienically sensitive applications. The housings comprise a flameproof enclosure and can be used even in the highest temperature class T6 in Zones 1 (gases) and 21 (dusts). Thanks to the enormous selection of interfaces, you will find the right rotary encoder for every requirement.

Our SIL3-/PLe-certified safety rotary encoders can also be provided with explosion-proof housings. They offer the perfect combination of functional safety and explosion protection in a single rotary encoder, for use in excavating and conveying systems, for example. For lower explosion protection requirements we also offer a SIL3/PLe rotary encoder, which can be used in Zones 2 and 22.
